Interpolation
Operation that consists of constructing or estimating the value of a function for a value of the variable taken between two discrete values in the interval in which the relationship was established.
Example
Starting from the values of [latex]\log(5)[/latex] and [latex]\log(6)[/latex], we can estimate using interpolation the value of [latex]\log(5.5)[/latex]:[latex]\log(5.5) ≈ \log(5) +\dfrac{\log(5) + \log(6)}{2} ≈ 0.738[/latex].
